Jerry is right to highlight assumptions. If the school is at the edge of a suburban area and very little school traffic goes across the crossing then risk might be acceptable. If we were to imagine that situation, do we need to take into account that the suburb may expand with housing built on the other side of the crossing making greater road/pedestrian traffic predictable.
Note that I refer to UK mainline practices as that is my experience - so I am working on a project at the moment that will upgrade a number of AHBs to MCB-OD or MCB CCTV. My experience says a CCTV or OD crossing is always full barrier and therefore not what is intended in the first part of the question.
Referring to your experience you could be thinking about what was done to eliminate AHBs.
Upgrade options are therefore MCB-CCTV. MCB-OD, bridge, closure+diversion. plus what other mitigations of lower cost you can think of.
For full barrier crossings I wouldn't have thought repeaters of the crossing lights would make much difference to risk. Adding them on a half barrier crossing might help reduce pedestrian misuse by negligence (but not deliberate misuse).
